is there any way that you can post your RSS program file? ...
(no offense intended, but it seems like we've asked this before) ...
we'd love to help you with the questions that you're asking - but we could literally write a book on how to handle analog signals - and we don't even know at this point what types of modules you're using ... different hardware requires different answers ...
if you can NOT post the program just say so – and we'll try to come up with another line of attack ... I assure you it will be a LOT more difficult and time-consuming at your end – and at ours – but we WILL try to help ...
on the other hand, if you're allowed to ZIP the RSS file and post it, we can probably help you with a minimum of time and effort ...
the more we know – the more we can help ...
PS Edit ... if you can post the program, please also tell us EXACTLY what type of RTDs you're using ... in most cases, you can't set up the module configuration without knowing that information ...
